Internal Error: Sub-system: PGM_COMMON, File: /quartus/pgm/common/pgm_common_xml_parser.cpp, Line: 631 - Internal Error: Sub-system: PGM_COMMON, File: /quartus/pgm/common/pgm_common_xml_parser.cpp, Line: 631 Description Due to a problem in the Quartus® Prime Pro Edition Software version 25.3.1 and earlier you may see this internal error if you try to add multiple bitstream files in the Programming File Generator tool to generate a single image (non-RSU) .jic file for Agilex® 7 FPGA or Agilex® 5 FPGA devices. This is an invalid use case. Resolution (custom) To work around this issue : If multiple bitstreams are required, use the Remote System Update (RSU) flow to generate the output .jic file. If the additional files are data files, use the "Add Raw File" button instead of "Add Bitstream". A future version of the Quartus® Prime Pro Edition Software will give a more meaningful error message.
